The Davenport Screw Machine Won World War II

"The Davenport screw machine won World War II," Massimo Bonaldo said to me, as we ate kebabs in a rural village 40 minutes from the center of Hannover, where I was to attend the EMO Machine Tool Show the following day. Massimo is the technical manager of Tajmac-MTM S.p.A., the Italian headquarters of ZPS, one of Europe's top machine tool builders.

I had trekked throughout Germany the previous two weeks, visiting elite manufacturers and machine tools dealers. I had walked through state-of- the-art shops, packed with the latest INDEX MS machines, Hydromats and CNC machining centers. And now I found myself hanging out at midnight with three Italian ZPS technicians in middle-of-nowhere Germany, with one of the company's top engineers giving me a history lesson on the good old noisy American Davenport. The reason the Davenport won World War II for the Allies, Massimo explained, was that the Germans were using European single-spindle machines to bang out ammunition, while the Americans spit out bullets like mad with five-spindle Davenports. Times have changed since the days of American multi-spindle domination. Today Germany is the place to be to see tons of manufacturers full of the best multi-spindle screw machines on the market. That's why Graff-Pinkert sent me there to find machines.

The first shop I visited on my trip was Brehm Präzisionstechnik GmbH & Co. KG, about 100 km southeast of Stuttgart. ...

ACME GRIDLEY 1-5/8" RBN-8 Rebuild

August 22, 2013 - 2:09pm -- Noah Graff
ACME GRIDLEY 1-5/8" RBN-8, Refurbished by Graff-Pinkert
Graff-Pinkert has several excellent ACME GRIDLEY 1-5/8" RBN-8 machines in stock. The ACME 1-5/8" RBN-8 was the latest design ACME GRIDLEY produced for that size diameter. The machine's frame is the same as that of an ACME 1-1/4" RB-8 making it smaller than its predecessor model, the ACME 1-5/8" RB-8. It has a significantly quicker indexing time than the 1-5/8" RB-8, making it the preferred 8-spindle screw machine for many ACME shops.

Multi-Spindles Are Coming Back

Wickman 1" 8-Spindle at Graff-Pinkert

“What goes around, comes around.” It’s a dumb cliché, but it’s what I am seeing in the screw machine business today.

The cyclicality of business is playing out as the auto industry in North America pushes toward the magical 16 million units a year mark. Thank god for the F-150, now the “best selling car or truck in America.” Tradesmen are buying, businesses are buying, even Aunt Millie is buying a vehicle today, and most of them are put together in North America with millions of perfectly turned components also made here.

Add a revival in home building and all those unleaded brass fittings needed and it means a lot of spindles turning, after the up and down gutting of the traditional turned parts world over the last 15 years.
My guess is that one third of the shops that ran multi-spindle automatics have gone away since the wholesale outsourcing trend to China began in the late 1990s.

The Davy Crockett of Screw Machines

May 10, 2013 - 10:57am -- Noah Graff

Tim Haendle was pleased with himself when I talked to him Wednesday. He had bought 100 carbide inserts – used of course – for a hundred bucks at a Hoff Online Auctions Internet sale of a screw machine shop in St. Paul, Minnesota. He’ll regrind them for use on one of the 22 National Acmes he runs in his shop, buried in a forest in Mendocino County, 100 miles north of San Francisco.

Turning Iron Into Gold

May 6, 2013 - 12:20pm -- Lloyd Graff

I love the used machinery business because it is a competitive treasure hunt every day. It asks us for impossible calculations about realizable values for illiquid, flawed, sometimes rickety, filthy objects that often have little tangible worth when we are asked to buy them.

Here’s an example of the type of situation we consider at my company Graff-Pinkert every day. A firm has a 25-year-old screw machine or rotary transfer machine that it does not need at the moment. It has long been written off the financial statements, yet the potential seller feels it still has value but doesn’t know how much. He calls dealers for comps, checks eBay for similar machines, and considers whether he may use it again soon himself. He advertises it or calls us and probes for an offer. We feel the piece may have enough potential value that would make it a worthwhile addition to our stock, but we need to determine whether it is badly worn and will require substantial expensive refurbishing, or if it can be sold in its present state, which usually means full of oily chips, a nasty appearance, and out of production.

If by chance the machine shows well and is still running good parts, it becomes inviting for our broker competition, which hopes to turn it quickly for a modest but quick profit, without doing any of the difficult work of returning it to its original state of productivity.

Life After the Breakup

I bought out my brother Jim’s interest in Graff-Pinkert six months ago. I promised him that I would not write about the breakup, but I want to take a few lines to describe how the post breakup is going for me.

The day after our deal closed I was vacationing with my wife, my sister and brother-in-law at the Chautauqua Institution near Jamestown, New York. (We had planned this trip a while before with my sister. That the breakup with Jim culminated at the same time was an odd coincidence.) The four of us were having lunch on the grounds when my iPhone rang and Jim’s name came up. I gulped, walked outside and took the call.

Jim quickly got to the point. There was a deal available with Wickmans and Hydromats. He had already looked at it. He wanted to know if I was interested in buying it. My head spun. Was this déjà vu? Was it 2012 or 2011? We had just broken up a 40-year relationship and now he was calling me to work on a deal?

“Well, uh, yes,” I stammered back. “Sure.” It was a pretty short conversation. This was not exactly how I expected my first day of solo ownership of the family business to go.
